The status of sensor market gradually highlights that the industry will usher in great development space.

The Annual Report on the Development of the Internet of Things in China 2017-2018 (hereinafter referred to as the "Annual Report"), published by the Jiangsu Center of China Economic Information Society, was published in Wuxi on September 14. According to the Annual Report, a new round of sensor R&D boom is emerging in China, and the market position is gradually highlighted. At present, a relatively complete industrial chain has been formed.

Sensor is the "five senses" of the Internet of Things, which is used to collect various kinds of information and convert it into specific signals. It is also an important symbol of the development of science and technology. In recent years, with the trend of integration of technology, sensors are gradually moving towards modularization and miniaturization.

The global sensor market has maintained a steady growth in recent years due to the worldwide emphasis on the research and development of sensors and the increasing demand for sensors in the market. In 2017, the global sensor market size exceeded US $200 billion, reaching US $207 billion 500 million, with a growth rate of 14.7%.

From the perspective of market distribution, there are more than 6500 global sensor production and production units. The United States, Europe and Russia respectively engage in sensor research and production of more than 1000 manufacturers, Japan has more than 800. But GE sensors, Emerson, Siemens, Bosch, Italian-French Semiconductor, Honeywell, ABB, Yokogawa, Omron, Schneider Electric, E+H and other leading companies in the United States, Japan, Germany occupy a total of nearly 70% of the market share.

At the same time, a new round of research and development upsurge of sensors is emerging in China, the gap between China and the advanced sensor technology countries is gradually shortened, and the market position is gradually highlighted. At present, a relatively complete industrial chain has been formed, and the level of materials, devices, systems and networks has been constantly improved, with more than 6000 independent brands.

The regional industrial clusters of the Internet of things have sprung up. Nearly half of the sensor enterprises in China are mainly concentrated in the Yangtze River Delta region, and gradually form a regional spatial layout with Beijing, Shanghai, Nanjing, Shenzhen, Shenyang and Xi'an as the main cities.

In recent years, China's sensor market continues to grow rapidly, with an average annual growth rate of more than 20%. According to the "China Sensor Manufacturing Industry Development Prospects and Investment Forecast Analysis Report" issued by Prospective Industry Research Institute, the sensor market size in 2011 was 48 billion yuan, and reached 112.6 billion yuan by 2016. In 2017, it increased to 130 billion yuan, an increase of 15.45% over the same period last year. Among them, flow sensors, pressure sensors, temperature sensors occupy the largest market share, accounting for 21%, 19%, 14% respectively; in the application field, industry, automotive electronics, communications electronics, consumer electronics accounted for the largest proportion, only the industrial and automotive electronics products in the field of sensors accounted for about 42%. In addition, the fastest growing areas of application are automotive electronics and communications electronics.

As the heart of the Internet of things, sensors have huge room for development. The system architecture of the Internet of Things is generally composed of perception layer, transmission layer and application layer. The perception layer is mainly composed of sensors, microprocessors and wireless communication transceivers. It is estimated that the economic benefits of the Internet of things will be between 2 trillion and 700 billion and 6 trillion and 200 billion dollars by 2025. Among them, sensors as the entrance of data acquisition, the "heart" of the Internet of Things, will usher in a huge space for development.

At the same time, due to the current domestic smart sensor foreign brands occupy the majority of the market share, the domestic imported products have a very large space for substitution. With the accelerated development process of local enterprises and smart sensor industry chain layout, China's smart sensor market will maintain a relatively rapid development rate in the future, the localization rate will continue to increase.
